CSV Format Guidelines
- Use commas to separate fields. Each line is a row.
- The first row is typically treated as column headers by Excel and other spreadsheet software.
- Wrap fields containing commas, quotes, or newlines in double-quotes:
"field, with comma" - To include a literal double-quote inside a quoted field, double it:
"He said ""hello"""
FAQ
Can I use semicolons or tabs as delimiters?
This tool expects comma-delimited CSV. If your data uses semicolons or tabs, do a find-and-replace to swap them for commas before pasting.
Will number formatting be preserved?
Values are stored as-is. Excel will auto-detect numbers, dates, and text. For precise formatting, adjust columns in Excel after opening.
Is there a row limit?
No hard limit from the tool. Excel supports up to 1,048,576 rows. Very large datasets may cause the browser to slow down during conversion.
